Do you mean something like the 4.4BSD namei interface where the VOP_LOOKUP
routine get the entire remaining path and is allowed to resolve as much of
it as it can (or wants)?

While this allows remote filesystems to optimize deep tree traversals it
creates a pretty big mess about state that is kept on lookup operations.

For Linux in particular it would mean doing large parts of __link_path_walk
in the filesystem, which I can't thing of a sane way to do.
